The New South Wales Attorney-General has announced an appeal to seek a longer prison sentence for former doctor Graeme Reeves, who removed a woman's genitals without her consent.

The former gynaecologist was sentenced earlier this month to a minimum of two years in jail for maliciously inflicting grievous bodily harm to Carolyn DeWaegeneire.

Reeves's maximum sentence of three-and-a-half years also covered his conviction for indecently assaulting two other female patients and obtaining financial advantage by deception by carrying out obstetric procedures despite being banned from doing so.

The former doctor was working at Bega on the NSW south coast at the time of his crimes.

Attorney-General Greg Smith says the state's Acting Director of Public Prosecutions has advised the sentence can be challenged on the basis it was "manifestly inadequate".

Ms DeWaegeneire was highly critical of the jail term handed down by the NSW District Court.

"My sentence is for life. I am an innocent person. I went to a hospital, by a registered doctor who is supported by all the bureaucratic 'up there' people," Ms DeWaegeneire said at the time.

"You go in. Never did I consider for one second he was going to do what he did.

"I was hoping a woman would be considered equal to a man. If a penis and a scrotum had been cut off, what sentence would you give to him?"
